Input Celsius and convert it to Farenheit

hey guys, Im new to C++. I've tried to solve the problem but no luck. My code will be shown below. Please advice me where I went wrong. Thanks

Write a program that reads a Celsius degree in double, converts it to Farenheit, and displays the result. The formula for conversion is: farenheit = (9/5) * Celsius + 32;
(Note: 9/5 is 1 in C++, so you need to use 9.0/5)
